Whitey if your daughter was able to ski to mid station i dont think she would have to much trouble doing the Musala pathway. The views are fantastic well worth the effort
The Musala is harder than the Royal Residence run. The run is steep in places, sharp turns and narrow pathways. When we were there at Christmas a man had a very very serious accident on the Musala, last we heard was that he was undergoing brain surgery in a US military hospital in Turkey.
The Musala is a challenge to a beginner, and is made more so by the attitude of others on the slopes.
